RE-1B Reference electrode (Ag/AgCl)
3M NaCl is used as an internal solution.
This is the standard type of aqueous reference electrode.
 |
| Reference potential |
| AgCl+e=Ag+Cl- E0=195 mV vs RHE (25 deg C) ∗ The reference potential is the measured value using RHEK reversible hydrogen electrode kit (Cat. No. 013597). |
RE-1BP Reference electrode (Ag/AgCl)
3M NaCl is used as an internal solution.
This is the standard type of aqueous reference electrode.
 |
| Reference potential |
| AgCl+e=Ag+Cl- E0=196 mV vs RHE （25 deg C） ∗ The reference potential is the measured value using RHEK reversible hydrogen electrode kit (Cat. No. 013597). |
RE-1S Reference electrode (Ag/AgCl)
Small size for the standard type (RE-1B).
 |
| Reference potential |
| AgCl+e=Ag+Cl- E0=195 mV vs RHE (25 deg C) ∗ The reference potential is the measured value using RHEK reversible hydrogen electrode kit (Cat. No. 013597). |
RE-1CP Reference electrode (Ag/AgCl/Saturated KCl)
Aqueous reference electrode with a saturated KCl as an internal solution.
 |
| Reference potential |
| AgCl+e=Ag+Cl- E0=198 mV vs RHE (25 deg C) ∗ The reference potential is the measured value using RHEK reversible hydrogen electrode kit (Cat. No. 013597). |
- Material: Polymethylpentene is used, because of the excellent chemical resistance characteristics.
- Liquid junction: Ceramics is used. (∗If you keep the electrode immersed in an alkaline solution for a long time, life time will be shortened.)
RE-3VT Reference electrode screw type (Ag/AgCl)
Aqueous reference electrode specific for ALS line-up flow cell, as Cross flow cell, Radial flow cell, EQCMT flow cell and SEC-３F Spectroelectrochemical flow cell.
 |
| Reference potential |
| AgCl+e=Ag+Cl- E0=195 mV vs RHE (25 deg C) ∗ The reference potential is the measured value using RHEK reversible hydrogen electrode kit (Cat. No. 013597). |

∗ IPPG: Ion Permeability Porous Glass
∗ Keep the reference electrode in a cold dark place.
∗ Take care when you open and unseal the electrode. The liquid junction tip could be taken out when you pull the black protector.
∗ RE-3VT is specific for ALS line up flow cell, it could be incompatible with other brand flow cell.
